Are there any professional tennis players in here? They will understand. I'll tell you what's going right. Serve: Fortunately I have a good working relationship there, the ball is happy with my serve. On the backhand the ball is also happy and we work together well and hit beautiful lengths. What I mean by the "ball being happy", is that the ball is hitting nice and smooth with good lengths, no technical hitches or issues.. BUT.... There's one part of our relationship that is not working very well at the moment ever since my coach added a change to my forehand and he did that so I could hit my forehand with great lengths instead of coming up with short lengths against the players who hit up to 120 mph on their strokes. . But now since the change, the ball is giving off a totally different attitude, it is upset, otherwise if ball was happy I wouldn't feel that repelling horrible feeling coming from it, the ball is saying in its own way, it dosen't want to work with me anymore, it dosen't recognize me and thinks I'm a stranger because of the new change it dosen't like.
